[Xen-users] XCP - iscsi problems

Hi list,

I'm having problems with iscsi errors in my 3-node pool logs.

The last time i tried to add a SR it took 4 tries (create/delete) where the pool master only are given 1 or 2 paths to the SR (needs 4)

This has happened before.

I have iscsi and multipath errors in the logs (see below)

Any ideas how to fix these problems, or what could cause them?

Anybody knows if it's safe to restart iscsi?

It seems that Dell OMSA could cause problems maybe like these, anybody aware if this is still an issue?

Thanks for any input.
